discussion group)
(1)
The aria spec currently states
(http://www.w3.org/TR/wai-aria/#host_general_role) that role must be a
space-separated list. It does not bar two of these tokes both being
aria roles.
Therefore it is possible to have multiple aria roles on the same
element. Is this intentional?
(2)
The html spec currently states
(http://dev.w3.org/html5/spec/Overview.html#annotations-for-assistive-technology-products-aria)
that role may not be used in "conflict with the strong native
semantics".
(2a) If it is possible for an element to have multiple roles, how
is conflict possible?
(2b) Does an explicit author-assigned role augment or replace the
roles derived from native semantics? (And is the answer different for
strong vs weak native semantics.)
